Hi Philip. Hope this bit of info is not too late for you.
I replaced my '05 Jazz filter at 115,000 km last October. Yes it was fiddly but I won't have to do it for another 100,000 km.
I was advised by a competent mechanic to leave it alone if my Jazz was not playing up (which it wasn't).
But the hypochondriac in me decided to go ahead with it. Yes it's located under the plastic consul very close
to the handbrake. Removing the front passenger seat (4 bolts only) makes removing the consul easier.
Make sure you disconnect battery (or remove fuse) and release the fuel tank pressure first !!
Silly me... when I disconnected the fuel hose... the petrol kept coming and I kept mopping ...
until it dawn on me about releasing the pressure in the fuel tank by undoing the fuel cap.
Sourcing the fuel tank cover removing tool was expansive and difficult, instead I used 2 large
and long screw drivers to leverage it off. An extra pair of hands to remove the cover certainly helps.
With your approach, do be careful with tapping the cover off in case you damage it.
Worth your while to take photos before you dismantle the fuel filter & pump assembly.
Having said that, I did not have a camera handy on that day - I wasted an hour figuring
how to reassemble the lot ! :(
Oh, the whole contraption is spring loaded. When I tried to put it back the assembly
was standing 50mm higher above the cover. Drrrr.. Just push it down carefully and tighten
the cover over it. Reconnect hoses and double check everything's in place and cover is tight.
It took me 3 hours because I made mistakes plus it being the first time I was extra careful.
Next time it'd probably take only 1.5 hours.
Having said all of the above, I take no responsibility if you have any problems.
PM me if you need any assistance on this matter.
Good luck.
